it now provides the fastest 4G LTE download speeds in New York City. Certain devices are able to take advantage of speeds in excess of 100Mbps.

The network, which has gone under various names before being dubbed LTE Plus last November, aggregates Sprint’s spectrum holdings in the 800 MHz, 1.9 GHz and 2.5 GHz bands to bolster coverage and capacity. Sprint claims the spectrum cocktail contributes to peak network speeds in excess of 100 megabits per second, better reliability due to the use of the three spectrum bands and hardware enhancements in the form of smart antenna technology designed to extend the cell signal for the coverage challenged 2.5 GHz band.
